INK-TABLE FOR PRINTING-MACHINES.

EBPECIFICATION forming part of Letters Patent No. 330,533, dated November 17, 1885.

Application filed May 14, 1884. Serial No. 131,447.

To aZZ whom it may concern:

Be it known that I, EDMOND A. WARREN, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Ink-Tables for Printing- Machines, of which the following is a specification, reference being had to the accompanying drawing, forming part of this specification.

This invention relates to ink-tables the surfaces of which comprise the faces of two rotary disks arranged side by side.

The object of this invention is to simplify such tables and the mechanism for operating them; and to this end the invention consists in the combination of two such disks, having on their peripheries matching projections, whereby they are caused to so engage with each other as to form of themselves a complete table capable of distributing the ink along the whole length of a roller without interruption, and that rotary motion imparted to one will be transmitted directly through it to the other.

The drawing represents a face view of an ink-table constructed according to my invention, and a longitudinal view of a pair of inkrollers applied to said table.

A A are the two circular disks, having in their peripheries projections a a and recesses b b, which match in such a manner that the projections on the one engage with the recesses in the other, like the teeth of spur-gear wheels. These disks have their faces perfectly flat and arranged in the same plane, so that they constitute sections of one ink table. They are supported and maintained in proper relation and engagement with each other by being fitted with or to central axles or journals (indicated by the dotted circles c 0,) supported in the printing machine or press in any suitable manner, according to the form or construction of the said machine or press. To one of the said disks a rotary motion is given by a ratchet and pawl or other suitable means such as are commonly employed or suitable for giving motion to a rotary inktableand the other disk receives motion from the first one through the projections and re cesses a b in their peripheries.

BB are the ink-rollers, of which there may be any suitable number, but of which two are shown, their length .being sufficient for them (No model.)

to reach across both disks A A. These rollers may be supported and operated in the same manner as in any of the printing-presses in which a rotary ink-table is used. They are represented as having bearings in two yokes, e e, fitted loosely to a shaft, d, which is firmly secured in two arms, O O, which have a reciprocating motion imparted to them by any suitable mechanism that will cause the rollers to move back and forth across the table. As suchmechanism constitutes no part of this invention,and is well understood, I have not thought it necessary to represent it, but will mention that the mechanism described for the purposein my application No. 131,446, filed May 14, 188i, for Letters Patent for improvements in numbering-machines, is suitable.

This improved ink-table is applicable to various kinds of printing machines and presses. It occupies muchless room than a rotary ink-table of the same width consisting of a single disk, while it obtains at least as perfect if not a more perfect distribution of the ink, the ink being distributed by the rollers from one disk to the other by the rollers passing over the intermeshing projections at a. The said projections on each disk, entering the corresponding recesses or spaces in the other one, produce such a continuity or sequence of contact between the ink-rollers and the disks that the ink is distributed without interruption along the whole length of the roller, and hence the two disks constitute in themselves a complete table, instead of being simply adjuncts of another table, like the disks shown in expired Letters Patent No. 62,032; and, moreover, the said projections cause one disk to transmit rotary motion directly to the other without requiring any other gearing between them or a EDMOND A. WARREN.
